Question

A cylinder has a radius of 12 m and a height of 9 m.

What is the exact volume of the cylinder?


A. 108π m³

B. 216π m³

C. 972π m³

D. 1296π m³

Answer 1

(D)

Explanation:

It is given that a cylinder has a radius of 12 m and a height of 9 m. Then,

Volume of the cylinder is given as:

`V={\pi}r^(2)h`

⇒
`V={\pi}(12)^2(9)`

⇒
`V={\pi}(144)(9)`

⇒
`V=1296{\pi}m^3`

Therefore, the volume of the cylinder is
`1296{\pi}m^3`.

Thus, Option D is correct.

Answer 2

we are given

radius=r=12m

height=h=9m

now, we can use formula of volume of cylinder

`V=\pi r^2 h`

now, we can plug values

and we get

`V=\pi (12)^2 *9`

we get

`V=1296 \pi m^3`

so, the exact volume of the cylinder is
`1296 \pi m^3`..........Answer
